well, let's start by figuring out the possible arrangements for Maria and Olivia M O _ _ _ _ _ _ M O _ _ _ _ _ _ M O _ _ _ _ _ _ M O _ _ _ _ _ _ M O _ _ _ _ _ _ M O I listed out 6 possibilities here, but we can also reverse the M and the O so that doubles our options, giving us 12 (we're not done yet though)

the next step is to consider how the other five people will be arranged in the 5 empty seats there are 5! ways to arrange the other people, and 5! = 120 now we just multiply 12*(120) to get 1440
